Just a Gryphaea, or something else? Yorkshire fossil ID please

Found near Whitby, Yorkshire in early Jurassic rock. Could just be a Gryphaea but I thought the curve looked a bit suspicious, like it was a more elongated structure, so figured it was worth checking. Thanks in advance.

Belemnite phragmocone indeed. They're quite common in nodules (and flattened in shale) in some beds of the Yorkshire Toarcian though are generally rare elsewhere.

 

This looks as if it may be from the Grey Shale Member of the Whitby Mudstone Formation (lower Toarcian) in which case it belongs to Passaloteuthis bisulcata.

If from higher up, it would most probably be Acrocoelites sp. but there's no way of identifying for sure without the accompanying rostrum (guard).
